China Zero-Covid Risk Level Dataset

This dataset records the county-level COVID-19 risk levels from April 2, 2021, to December 15, 2022, with daily frequency. The data was sourced from the Chinese State Council’s public website for COVID-19 risk levels (the original site is no longer active). Risk levels are categorized into three classes: high risk, medium risk, and low risk. Until July 21, 2022, only regions designated as medium or high risk were publicly listed, with all other areas classified as low risk. From July 21 to November 15, 2022, the website expanded to include low-risk areas as well, marking all other regions as under “normal preventive control.” Starting November 15, 2022, only high-risk and low-risk regions were listed, with other areas still under normal preventive control. For details on these adjustments in risk definitions, please refer to related policy documents and reports. The dataset includes binary status variables for both high_risk and mid_risk levels, where a value of 1 indicates that a county contains at least one area classified as high or medium risk, respectively. Please note that a county may simultaneously contain both high- and medium-risk areas, resulting in both high_risk and mid_risk being marked as 1. This dataset has been cleaned to the county level, though the original data included some street-level information. Researchers interested in the original finer-level details should contact the authors directly. The dataset, along with additional notes, is available at: https://github.com/dadasmash/China_COVID_Risk_Level_Dataset/tree/master For further details on the dataset’s structure, please refer to the original publication.

Contributors: Da Gong, Andong Yan, Qi Zhang本数据集按日更新，记录了2021年4月2日至2022年12月15日期间的县级新冠疫情风险等级。数据来源于中国国务院新冠疫情风险等级公开官网（原站点现已无法访问）。风险等级分为高风险、中风险与低风险三类。 2022年7月21日前，官网仅公布中高风险地区，其余区域均归类为低风险地区；2022年7月21日至11月15日期间，官网扩展公布范围，新增低风险地区，其余区域标注为“常态化防控区域”；2022年11月15日起，官网仅公布高、低风险地区，其余区域仍为常态化防控区域。有关风险等级定义调整的详细信息，请参阅相关政策文件与官方报道。 本数据集包含高风险（high_risk）与中风险（mid_risk）两类二元状态变量：变量取值为1时，分别代表该县域内至少存在一处高风险区域或中风险区域。需注意，若某县域同时包含高、中风险区域，则high_risk与mid_risk变量均会被标记为1。 本数据集已整理至县级粒度，原始数据最初包含部分街道级别的细节信息。若研究人员需要原始的细粒度数据，请直接联系数据集作者。 本数据集及附加说明文件可通过以下链接获取：https://github.com/dadasmash/China_COVID_Risk_Level_Dataset/tree/master 有关数据集结构的更多细节，请参阅原发表论文。若您使用本数据集，请引用如下文献： • 龚达、尚卓成、苏雅琴、严安东、张琦：《中国新冠疫情清零政策的经济影响》，载于《中国经济评论（China Economic Review）》，第83卷，2024年，文章编号102101，ISSN 1043-951X，https://doi.org/10.1016/j.chieco.2023.102101. 数据集贡献者：龚达、严安东、张琦
